You would more than likely just have to fabricate components. Mopar performance does swap for all the early cars, but nothing for a truck. However, the truck mounting surface is just a hole in a piece of metal, nothing special.
The easiest way of doing this, and it has been done, is take the existing motor mounts off that hemi, along with engine measurements and fabricate new ones. It would honestly be really easy even for a novice welder, or a shop would be able to do it for you. Just make sure you've measured properly so that your engine fits in your engine bay.
Beyond that, just go with some tight shorty headers. Your steering shaft is gonna be a bitch if you try to make long tubes work. Even just a nice set of manifolds would be fine. And then all you'd need is an adapter plate on your existing tranny crossmember to move the attachment point forward or backward, depending where the transmission sits. You'll also need to shorten or lengthen your driveshaft, and depending on what yoke it has on it now, you may need to swap that out too.
If you're good with a welder and have a reliable driveshaft shop around, this could all be done on a saturday and you'll be good to go.
